The System Dynamics Characterization and Controls Laboratory of Sun
Microsystems has developed novel continuous system telemetry
technology for proactive fault monitoring and “electronic prognostics”
capabilities for all types of executing computing platforms. Central
to the goal of designing and evaluating prognostic and control systems
for enterprise computing platforms is first the ability to simulate
telemetric signals and computer system degradation events with
real-time models in an interactive computer environ- ment. This paper
describes the development and implemen- tation of a Telemetric
Parameter Simulation System (TPSS) that employs Fourier-based
decomposition and reconstruction methodology with the capability to
efficiently decompose any signals into their deterministic and
stochastic components, then reconstruct new, simulated signals that
possess exactly the same statistical noise idiosyncrasies as the
original telemetry variables. The TPSS has become an indispensable
tool in Sun’s ongoing development of innovative diagnostic techniques
for telemetry operability surveillance and other electronic prognostic
applications in enterprise in Sun’s present and future computer
platforms.
